An anti-fire protection device for a starter-controller device of an electrical installation is able to be connected to an electrical power conductor and includes thermal monitoring of the electrical power conductor to detect a temperature rise of greater than a predetermined threshold. This anti-fire protection device can be fixed mechanically to the starter-controller device via at least one mechanical linking member. The thermal monitoring includes at least one temperature sensor and a cartridge including a fire extinguishing agent and at least one injection element, situated on the same face of the protection device as the temperature sensor, the cartridge being situated inside the protection device and connected to the temperature sensor, the injection element being able to inject the fire extinguishing agent towards the electrical power conductors subsequent to a detection, by the temperature sensor, of a temperature of greater than the predetermined threshold.

An electromagnetic actuator comprising a core moving between a latched position and an open position, a permanent magnet, a coil designed to generate a first magnetic control flux to move the core from an open position to a latched position, and a second magnetic control flux designed to facilitate movement of the moving core from the latched position to the open position. The permanent magnet is positioned on the moving core so as to be at least partly outside the fixed magnetic circuit in which the first magnetic control flux flows in the open position, and to be at least partly inside the fixed magnetic circuit used for flow of a magnetic polarization flux of the magnet in the latched position.

An electromagnetic trip device comprising a shell and a moving core sliding due to the action of a coil, the shell comprising a radial surface having an opening through which the moving core passes, superposition of a radial crown of the moving core and the radial surface forming a magnetic flux transfer surface enabling flow of an axial magnetic flux. The trip device comprises intercalary adjustment means of said transfer surface respectively positioned between the moving core and the opening, said intercalary adjustment means comprising two calibrated elements adjoined surface against surface and being respectively formed by an alternation of magnetic sectors and non-magnetic sectors; movement of a calibrated element with respect to the other enabling a variation of said transfer surface to be obtained.

A screw terminal with creep compensation comprises a pressure device enabling a clamping energy of the terminal to be stored. According to the invention, means for detecting the tightening torque enable the user to identify the force required for connection and to check that the creep is in fact compensated. The means for detecting comprise an element securedly affixed to the pressure device and an element securedly affixed to a wall of the housing in which the terminal is fitted, the distance between the two elements being determined by means enabling indicating means to be actuated when the distance is smaller than a threshold corresponding to a predetermined tightening torque.
